Abstract

An Interactive Maintenance Management System (“IMMS”) (10) is an alarm handling system (FIG. 2) for handling alarms (102) that indicate present or imminent equipment failure. The IMMS (10) may be utilized in industrial situations, such as strip-mines (14), to reduce equipment (12) downtime and reduce or prevent equipment failure. The IMMS (10) utilizes a flexible response system to track, analyze, and improve performance of the alarm handling system.

Claims

1. A method of handling equipment failure alarms comprising the steps of:

receiving an alarm from a transceiver of a mining vehicle, the alarm indicating a state of at least one of a component and a system of the mining vehicle, the alarm including an abnormal event identifier and at least one of an equipment identifier, a location, and an equipment operator identification;

storing the received alarm in a database;

analyzing the alarm, by;

identifying a minimum health factor for at least one of the component and system of the mining vehicle,

identifying an occurrence frequency of the alarm,

determining whether the minimum health factor for the at least one of the component and system of the mining vehicle has been violated, and

using the determination of whether the minimum health factor has been violated and the occurrence frequency of the alarm to determine whether the alarm is to be snoozed;

when the alarm is to be snoozed, setting snooze criteria; and

when the alarm is not to be snoozed, releasing the alarm.

2. The method of claim 1, further comprising the step of when the alarm is not to be snoozed, displaying the alarm for action or information.

3. The method of claim 2, further comprising the steps of:

determining that a repair record is to be created; and

creating a repair record, wherein said steps of determining that a repair record is to be created and creating a repair record follow analyzing the alarm.

4. The method of claim 3, further comprising the steps of:

ignoring said alarm; and

documenting the reason for ignoring said alarm, wherein said ignoring step and said documenting steps follow the analyzing the alarm step.

5. The method of claim 3, further comprising the step of sending the alarm to an analyst.

6. The method of claim 5, wherein the analyst is a third-party.

7. The method of claim 1, further comprising the step of, when the alarm is to be snoozed, selecting snooze duration based on time.

8. The method of claim 1, further comprising the step of, when the alarm is to be snoozed, selecting snooze duration based on abnormal event frequency, wherein said selecting snooze duration step follows said determining that the alarm is to be snoozed step and precedes the step of determining that at least one of the snooze criteria has been violated.

9. A method of handling equipment failure alarms comprising the steps of:

receiving an alarm from a transceiver coupled to a mining vehicle, the alarm indicating a state of at least one of a component and a system of the mining vehicle, the alarm including an abnormal event identifier and at least one of an equipment identifier, a location, and an equipment operator identification;

analyzing the alarm, by;

identifying a minimum health factor for at least one of the component and system of the mining vehicle,

identifying an occurrence frequency of the alarm,

determining whether the minimum health factor for the at least one of the component and system of the mining vehicle has been violated, and

using the determination of whether the minimum health factor has been violated and the occurrence frequency of the alarm to determine whether the alarm is to be snoozed; and

when the alarm is not to be snoozed, displaying the alarm for action or information.

10. The method of claim 9, including evaluating whether a notification of the received alarm should be sent to a third party maintenance organization.

11. The method of claim 10, including, when notification of the received alarm should be sent to a third party maintenance organization, sending an alarm packet describing the received alarm to the third party maintenance organization.

12. The method of claim 9, wherein the mining vehicle includes at least one of a dozer, drill, haul truck, loader and shovel.

13. The method of claim 9, including:

determining that a repair record is to be created; and

creating a repair record.

14. The method of claim 13, wherein determining that a repair record is to be created includes determining a consequence of a failure of the mining vehicle based upon the alarm.

15. The method of claim 13, wherein the consequence includes a repair cost or a safety implication.
